I have an 87 GT, and it has been haveing a power issue, first it would bog down when accelerating (it accelerated very slowely), so i fixed the ignition timing and solved that problem. then it would accelerate fast, or go past 40 mph or 3000 rpm, i changed the catalytic converter, solved that problem. Now it excelerates, but it jerks and sputters when i stomp on it. according to the "fixer manual", it says i may have a bad EGC valve, but i checked that and it seems good. PLEASE HELP ME!! thanks justin
